Application of vacuum coating machine
Vacuum coating equipment is mainly refers to a kind of need to be done under high vacuum coating, including many types, including vacuum ion evaporation, magnetron sputtering, MBE molecular beam epitaxy, PLD laser sputtering deposition and so on many kinds. The main idea is to divide into evaporation and sputtering. The coating is called a substrate and the coated material is called a target. The substrate and the target are in the vacuum chamber.
Evaporation coating is generally used to heat the target material so that the surface components are vaporized by atomic or ionic forms and deposited on the substrate surface, forming a film through the forming process. For sputtering coating, can be simple to understand for the use of electronic or high-energy laser bombardment of target, and the surface components form groups of atoms, or ions was sputtering, and eventually deposited on the substrate surface, experience the film-forming process, eventually form a thin film.
Application of vacuum coating machine:
1. Soft packaging of food industry: biscuits and baking products, candy, coffee, tea, chocolate chip, soup, high barrier film;
2. Decoration: gift wrapping, trademark, hot stamping foil, holographic and so on;
3. A variety of technologies and commodities: aluminum wire for textile industry, sun protection film for construction and automobile industry, safety and anti-counterfeiting (holographic), capacitor film, electrostatic shielding (cable and electronic);
